Ugh, because this is one of those things I've done way too much

ios_to_android.rb

require 'fileutils'

class Tuple
	attr_accessor :first, :last
	def	initialize(first,last)
		@first = first
		@last = last
	end
end

ios_directory = "../ios-images/"
android_base_dir = "../app/src/main/res"
hdpi_dir = "#{android_base_dir}/drawable-hdpi/"
mdpi_dir = "#{android_base_dir}/drawable-mdpi/"
xhdpi_dir = "#{android_base_dir}/drawable-xhdpi/"


cleaned_file_names = Dir.entries("../ios-images/") 
						.reject{|file_name| !file_name.include?(".png") } 
						.map { |file_name| Tuple.new(file_name, file_name.downcase.gsub("-","_")) }


cleaned_file_names.each { |tuple|  
	
	if tuple.last.include?("@2x") 
		file = tuple.last.gsub("@2x","")
		FileUtils.cp(ios_directory + tuple.first,hdpi_dir + file)
	elsif tuple.last.include?("@3x")
		file = tuple.last.gsub("@3x","")
		FileUtils.cp(ios_directory + tuple.first,xhdpi_dir + file)
	else
		FileUtils.cp(ios_directory + tuple.first, mdpi_dir + tuple.last)
	end
}
